Beatrice has at least one quarter, one dime, one nickel, and one penny. She has exactly 13 coins total. Beatrice also has a total value of 92 cents. How many different sets of coins can she have?
Answer:
(Q, D, N, P) = (0, 7, 4, 2) or (1, 3, 7, 2)
Step-by-step explanation:
Let the numbers of coins be Q, D, N, P
We have:
Q + D + N + P = 13
25Q + 10D + 5N + P = 92
Obviously, P = 2, so
Q + D + N = 11 (1)
25Q + 10D + 5N = 90
Divide by 5 and get
5Q + 2D + N = 18 (2)
(2) - (1), get
4Q + D = 7
Let D = 7, Q = 0, from (1), N = 4, so the set is (Q, D, N, P) = (0, 7, 4, 2)
Let D = 3, Q = 1, from (1), N = 7, so the set is (Q, D, N, P) = (1, 3, 7, 2)
If D = 6, 5, 4, 2, 1, 0, Q is not an integer, these can be ignored.

The directions on a turkey tell you to cook the turkey 20 minutes per pound.
Part A: Write a function in function notation for this situation where X is the number of pounds.
Part B: Describe the domain of this function. Assume turkeys can weigh up to 30 pounds.
Part C: Graph this function and state the range.
Part D: Use this graph to determine the cooking time for an 18 pound turkey.
Answer:
Step-by-step explanation:
Let y be the time required to cook the turkey, and x the number of pounds of the turkey.
The time required, x, is equal to the turkey's weight (in lbs) times 20 min/lb.
y = 20(min/lb)x
The domain of this function is 0 - 30 pounds.
The cook time for an 18 lb turkey is y = (20min/lb)*(18 lb) = 360 min

You go to the store to buy a new TV that is $430. If the tax is 6% of that price, what is the total cost of the TV including tax?
Answer:
$455.8
Step-by-step explanation:
6% of 430 = 25.8
430 + 25.8 = 455.8
If you need further help, let me know.
- profparis
Answer:
$455.80
Step-by-step explanation:
Given the following question:
6% of 430
To find the answer we must first use the formula to calculate percentages to find 6% of 430. Then we add that answer to the initial price of the TV to have our final answer.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{6\times430}{100}[/tex]
[tex]6\times430=2580[/tex]
[tex]2580\div100=25.8[/tex]
[tex]=25.80[/tex]
Now add the answer to the initial price of the TV:
[tex]430[/tex]
[tex]430+25.80=455.8[/tex]
[tex]=455.80[/tex]
The cost of the TV after a 6% tax is "$455.80."
Hope this helps.

B The greatest common factor of 10 and 15 is 5.
C The greatest common factor of 13 and 21 is 3.
D The greatest common factor of 14 and 21 is 3.
Hi There!
The greatest common factor of 10 and 14 is 5 [FALSE]The greatest common factor of 10 and 15 is 5. [TRUE]The greatest common factor 13 and 21 is 3. [FALSE]The greatest common factor of 14 and 21 is 3. [FALSE]Step-by-step explanation:A factor is a number that a number can be evenly divisible by.Example: 5 is a factor of 10, because 10 can be evenly divided by 5.Example #2: 3 is not a factor of 13, because 13 is a prime number, which means it has only 2 factors - 13 and 1.3 is not a factor of 14. The factors of 14 are: 1, 2, 7, 14.5 is not a factor of 14 (reason - above)Hope it helps!Have an awesome day!

Kay's gross pay is $2,851. Her deductions total $491.22. What percent of her gross pay is take-home pay?
Show work for 80 points!!!!
Answer:
Her take home pay is $2359.78
The percentage is approximately 82.77%
Step-by-step explanation:
Gross is the full before tax or whatever.
$2851 - $491.22 = $2359.78
$2359.78 / $2851 = 0.827702
$2851 - $491.22 = $2359.78
$2359.78 / $2851 = 0.827702
so the answer is 0.827702
